Telling that it was an issue even though you overlooked it at the start. Don’t trust anyone who says it’s occasional. They are lying to you and to themselves.
I agree her suitor is probably addicted based on wanting to quit AND not being able to go a whole date without smoking--but I disagree everyone who marks "occasional" is lying. My sister has quit and restarted countless times--she's "occasional". My brother smokes a cigar when a friend's baby is born or a friend returns from Cuba--that's less than once per year--he's also "occasional". I don't know why most become addicted to nicotine and some don't. I'm not dating yet. When I do, this thread is making me think maybe I'll clarify "occasional" before a date as a potential deal-breaker. In the past, as a non-smoker, I've had the same reaction as Canbird.
